I have a narrow V shaped upper arch, will Damon clear braces be sufficient to widen the arch? Or would Damon metal braces be more effective as they are stronger? I would prefer Damon clear, and do not mind if they take a few months longer, however my query is whether a better, wider final result would be achieved with Damon metal braces? I currently have the Damon clear braces on however am considering to change them for metal ones
